System Design Scalability Data Handling
You can expect system design questions if you have 4+ years of experience.
- Scalability and System Design are very large topics with many topics and resources, sincethere is a lot to consider when designing a software/hardware system that can scale.Expect to spend quite a bit of time on this
- Considerations:
- Distill large data sets to single values
- Transform one data set to another
- Handling obscenely large amounts of data

How Do I Get Good Marks In Class 12 Cbse Examination If I Have Only 1 Month Left
2021-06-19 02:30:25
In my 12th Boards Accounts,I had attempted 97 marks and secured 95.
Well if you ask me what i did then my answer is i had mastered all the concepts. Well , i always found accounts to be interesting . In the first 6 months i had all my syllabus completed and used to teach my friends so it always helped me to have a control on my concepts. Not only for accounts but for other subjects as well.
Now coming back to your question ,if you are aiming to get 100 marks in accounts in one month and thinking whether it is possible or not then yes it is. In the last one month what i did was just practice and repractice. The book i kept with me was NCERT AND DK GOEL. I had solved all the illustrations and even exercises of some chapters given in DK Goel and i paid special attention to the past year questions . For me only one mantra worked , If your concepts are strong and you have practiced questions then nothing will go wrong for you . And the key to secure maximum marks is a good amount of revision.
Make a small register and when you practice , any adjustment or point which you thought important just note it down there . Mark the questions which you found difficult , now in the second revision practice these .
All the very best for your boards. Make use of this month to get the best result in the next month.

Learn About The Company
Needless to say, another preparatory piece of reading for you is learning about the company.
Some of the questions you should ask yourself are:
- What is its mission statement?
- Who is/are its CEO?
- How do I fit in the big picture?
- What appeals to me?
And so on. This isn’t elementary school, so, nobody is going to ask you directly about any of this. However, having a good understanding of these topics will lead to really sane conversations with the people you meet.
A Note About Video Resources
Some videos are available only by enrolling in a Coursera or EdX class. These are called MOOCs.Sometimes the classes are not in session so you have to wait a couple of months, so you have no access.
It would be great to replace the online course resources with free and always-available public sources,such as YouTube videos , so that you people can study these anytime,not just when a specific online course is in session.

Coding & Algorithm Interview
Google software engineers solve some of the most difficult problems the company faces with code. It’s therefore essential that they have strong problem solving skills. This is the part of the interview where you want to show that you think in a structured way and write code that’s accurate, bug-free, and fast.
Here are the most common question types asked in Google coding interviews and their frequency. Please note the list below excludes system design and behavioral questions, which we’ll cover later in this article.
Below, we’ve listed common examples used at Google for each of these different question types. To make these questions easier to study, we’ve modified the phrasing to match the closest problem on Leetcode or another resource, and we’ve linked to a free solution.
In addition, we recommend looking at the list of former coding interview questions and the interview tips that Google makes available. These questions aren’t used by the company anymore but are still useful for practice.
Example coding questions asked at Google
1. Graphs / Trees
2. Arrays / Strings
3. Dynamic Programming
4. Recursion
5. Geometry / Math
What If I Dont Get The Job
It wont be the end of the world.
Ive put the time and dedication into my studies for the goal of getting hired as a Google software engineer, but even if I fail, Ill still be armed with the skills and knowledge required to work as a software engineer at any company.
Wherever I end up, Im going in as an entry-level software engineer. Im not going in with 15 years of software engineering experience because I simply dont have it. When it comes to this stuff, Im the equivalent of a fresh CS grad.
But I have the enthusiasm of a new grad, too. This is a new world for me. Im just getting started. Im not afraid to make mistakes. I know I will. I also want to learn everything I can and be an excellent addition to any team.

Common Technical Interview Mistakes To Avoid
Knowing what not to do can be just as important as knowing what to do, so lets quickly cover a few common technical interview mistakes.
1. Not preparing enough
Seriously, theres no such thing as too much coding interview preparation. The good news is, most candidates dont put in that time. So it doesnt take much to really pull ahead of the pack, says Parker . Its such a bummer as an interviewer to watch a candidate really come up short and just think to yourself, I can tell youre smartif you had just reviewed some of this stuff Im sure youd be able to get this.
2. Jumping into the code without taking a moment to think it through
You might be eager to start solving the problem, but take a few minutes to question your assumptions and make a game plan first! Starting too quickly gets a lot of people into trouble when they could have taken a moment to prevent confusion down the road, says Refael . Some of the most common mistakes candidates make are avoidable. Pause for a moment to think through the problem-solving process.
3. Being too arrogant or opinionated
4. Not making conversation/chit-chat
Tip #1 Basic Knowledge Review
If I had to choose only one thing to prepare, I wouldnt even hesitate to get my basic knowledge reviewed.
Although this should be done at the first step of your preparation, you will still be surprised by how many people are confused about things like Big-O analysis. Thats why I think its essential to make sure you have a solid computer science foundation.
You dont need to read every page of Introduction to Algorithm, but its recommended to go over basic data structures/algorithms to make sure you are familiar with all of them.
I wont recommend too many resources as you have no time to check them. Here I would only list 2 sites: The Technical Interview Cheat Sheet and Big-O cheat sheet. Both are concise and provide a perfect summary of things you should know.

How To Prepare For An Interview In One Month
People always asked us what I should do to prepare for an interview within several weeks. This post is not teaching you any sort of shortcuts or tricks that let you get offers without efforts, instead we want to help you only focus on things that have huge impact on your preparation, thus compress your preparation time within a month. In addition well recommend only one or two resources in each section since theres no need for you to check a 300 page book or tens of websites.
Pareto principle teaches us that 80% of the effects come from 20% of the efforts, in other words majority of peoples preparation work only have trivial effects on their interview performance. The key to be efficient in preparation is not getting any super secret resources, instead is by eliminating useless effort and be more focused on those 20% work.
After interviewing a lot of Gainlo interviewers, its quite clear that certain preparation patterns/hacks do exist and they can definitely be compressed into weeks. In fact, many of them got their job offers only within 3 weeks preparation. Lets see how those guys including me are using this model and how you can do the same.
Day 0: Make concrete timeline and stick to it
I know its gonna be hard. For student, you may have lots of course work to do. And for employees, you just cant do it during work hour. But you should always figure out some time EVERYDAY. No time is no excuse.

My Guide To Preparing For The Google Technical Interview
TODO: Upvote my original post and other good answers on Quora. The following is my answer to the question “How should I prepare for my Google interview if I have 1 month left?”
With over ten years of programming experience and a CS degree, it took me about a month and a half of daily practice to get ready for the interview. Ready, for me, is ambitiously defined as the ability to tackle almost any technical interview question in 30 minutes or less and reach an optimal solution. The following is based upon what I did to prepareyour mileage may vary.
Ingredients:
- About two years of solid coding experience
- Pencil and paper
- Your favorite algorithms bookIntroduction to Algorithms, The Algorithm Design Manual, and Programming Pearls are a few good choices. Might I suggest you go low tech and buy physical copies?
- Two or three hours a day
- Highly recommended: Whiteboard
- Optional: MIT OpenCourseware or another learning site
Directions:
1) Learn as much as you can about the Google interview process
Just like an incomplete understanding of a technical question will ruin you in the actual interview, misinformation will derail your preparation leading up to it. I learned this the hard way when I failed at my first attempt after emphasizing brain teasers over studying algorithms and data structures.
Once you have a solid foundation, Id recommend following up by reading CTCI. Particularly focus on chapters 5 and 6 entitled Behavioral Questions and Technical Questions.
Weeks 4 & 5 Practice Simple Data Structure And Algorithmic Challenges
As you are familiarizing yourself with data structures, start practicing relatively simple coding problems associated with these data structures and algorithms.
These questions are typically not asked in interviews at big tech companies. Even if they are, theyre usually used as fizz-buzz type warm-up problems. Such questions are also common during phone interviews. However, practicing these coding interview questions will help you internalize the data structures and help you tackle the harder questions which youll be practicing a few weeks from now.
Brush up your array skills with questions like:
- Remove Even Integers from Array
- Merge Two Sorted Arrays
- First Non-Repeating Integer in an Array
- Find Second Maximum Value in an Array
Brush up your Linked List concepts with questions like:
- Find Length of Linked List
- Search in Singly Linked List
- Reverse a Linked List
- Find Middle Value of Linked List
Brush up your Stack/Queue skills with questions like:
- Sort values in Stack
- Create Stack where min returns minimum value in O
- Implement Two Stacks using one Array
Practice Tree Problems like:
- Find minimum value in Binary Search Tree
- Find Height of Binary Tree
- Find kth maximum value in Binary Search Tree
Practice Graph Problems:
- Total number of words in Trie
- Find all words stored in Trie
Practice basic Heap problems:
- Find k smallest elements in a list
- Find k largest elements in an array

Getting Noticed By Google
Google receives more than two million resumes but hires only around 4000 employees every year so its not easy to get noticed by recruiters for interview calls. Take the referrals through some connections working in these companies or you can take the help of LinkedIn and online coding platforms to increase your chances for interview calls. Below are some points that will help you in getting the call for interviews
How Long Should I Prepare For A Coding Interview
Coding interview preparation time largely depends on the interviewee’s level of experience. If you’re an entry-level programmer, it’s a good idea to spend at least twelve weeks preparing. If you have more experience, 4-8 weeks is suggested for interview prep.
Study the company’s programming language and tools of choice. Practice a couple of coding challenges each day don’t let your practice be a cram session right before your coding interview. Finally, as you practice, make sure to time yourself to see how you are progressing.

Tip #5 Know More About The Company
Prepare well for questions like why you want to join us. For many companies like Facebook, you will be asked for this question for sure.
More importantly, every company will evaluate the so-called culture fit. You should have a clear reason why you are best fit for this company and vise versa. From this perspective, doing an investigation to know about the company more than its name can make a big difference.
Also asking yourself why you want to join the company helps you better understand whether you are making the right decision. I encourage people to work for companies that resonate with them, otherwise, you might end up with a terrible work life even if you get paid well.
Do Research On The Company And Try To Understand What To Expect
At this point, you’ve been practicing general strategies and hopefully have a framework that you’re going to follow once you’re in your interview. I generally don’t recommend spending lots of time on company-specific interview prep, but now is the time to bring some of that into your process.
Do some research on the company. What are they looking for in the role? What did the job description say?
Go on Glassdoor and see what sorts of interview experiences other people had. Are there any specific topics that keep coming up again and again?
Does the company have specific leadership principles like or do they do some unique type of interview?
This is the time to figure out so that you can be fully prepared.
